SP30AP Audiophile and Flex 6000 Series

When I bought my 6300 (Recall
I was at Vegas 2014) ....I never thought I was going to dig so deep in my radio
hobby....

Before Flex...my ham
amateur life was simple (boring) power supply, cables, any antenna and a lot of
noise from my Kenwood TS480 ......I never was worried about
RF...spurials or out phases waves....I didn't even note those
"things" existed...haha

Now my life is full of
new challenges every day....looking for minimal RF interference (thinking about
RG400/u Jumpers)....zero spurial (utopic) ...Quiet station (following advises
from KY6LA), although I know I broke one rule and bought (02) two IOTA switching
power supply....

Today comes to my mind
when I asked to this community about speakers, many of you helped me!!!
recommended Bose Companion Speakers....they have been wonderful...good sound
and stereo...I don’t know yet if I really understood SDR stereo
audio....sound is good....recently I bought a Dual in-line Noise
Eliminating Module by BHi Uk (still trying to figurate out)....

So finally, I wondered.....do
I need to get a new and more professional speakers?

Began to look around
and found Palstar new SP30AP Audiophile....it’s no big....perfect for my shack...
expensive 350$ plus shipping. Reviews
about Palstar speakers are good to Excellent, some of those says “hear things and never heard before”.....mmmm?????

So, here are my Open
questions: Does Anyone have experience with Palstar Speakers? would Flex 6300
(6600 on future) work good with only one speaker? I understand Palstar is not
powered speaker, audio power from flex will be enough to “move” it?

I would certainly stick with the Bose at the moment, because there is only so much we can squeeze out of Ham radio audio. Unless of course you are looking for new toys - which is always a valid reason to buy something new!

I do believe you will need an amplifier for the Flex audio out.

I've thought about installing a tube amp for my system, sort of a old school addition to a modern SDR radio. Right now I'm using Monsoon's, who are out of business.

I have a couple of Palstar SP30H speakers. They are not powered speakers as the FLEX 6xxx radios require. The SP30H are the finest sounding HAM speakers I have ever heard. I use them on other than the FLEX.

On my FLEX 6500 I use a set of JBL Control 2P 35 watt speakers. They are very good. Got them on AMAZON, also at Guitar City and other places.

I have used a pair of KRK Rockit 5" powered studio monitors for several years now. Great sound and studio quality connectors for balance and unbalanced inputs. I usually feed them through a Scarlet 2i2 audio interface via SmartSDR. They retail for around $300 a pair, but can be found around $250 to $275 online. They could be connected directly to the Flex with the appropriate adapters. Studio monitors can be the way if you are looking for accuracy. You just have to do your research though. As far as PC speakers go the Audioengine A2+ series usually gets good reviews at around $250 a pair.

When considering audio equipment, you have to consider what it is that you're listening to. In the case of amateur radio, you need good fidelity, which also depends on the signal quality. You will be listening to single sideband or CW, both of which only require a good speaker to get the best sound reproduction.

In the case of music, you need superior quality with wide a wide range of highs and lows. Of course, a speaker capable of producing that quality is much more expensive. However, that doesn't necessarily make it a better speaker, just one that can reproduce a wider range. You may even need more than one speaker and multiple audio outputs to hear the entire range.

Here's an analogy: You can drive a Ferarri on any American freeway but you still are limited to 65 miles per hour. While the Chevrolet in the next lane costs much less, it's capable of achieving the maximum legal speed, therefore gets you there just as quickly. The biggest difference is that not as many girls will check you out on the way.

While stereo isn't totally necessary for our ham radio purposes, it's nice to be able to have the DX in one ear and everyone else in the other, maybe muted in volume, when working a pileup.
